IMPROVEMENT IN LOOMS FOR WEAVING PILE FAB RIOS.

Specification forming part of Letters Patent No. 211,949, dated February4, 1879; application filed January 11, 1876.

the accompanying drawings.

The nature of my invention consists, first, in combining, with awire-box which is so constructed that its upper surface, or the partthereof contiguous to the point where the heads of the wire come incontact with the box, is somewhat lower than the upper surface of theheads of said wires, a vibrating wire-bar and a reciprocatingdriving-slide carrying a hook,

which driving-slide is adapted to move on the said wire-bar, whereby thesaid book, after it I has inserted a wire, passes over the heads of thewires without coming in contact with the upper surface of the box to theproper position for seizing and withdrawing another wire; and, second,in combining, with said wire-box, vibrating wire-bar, driving-slide, andhook, a spring-director, whereby the said hook is prevented fromrebounding and engaging with the head of an adjoining wire.

In the drawings, Figure 1 represents a top view of a loom, in part,having my improvement applied. Fig. 2 represents a front View of myimprovement, the wire-box and the wirebar shown partly in section. Figs.3 and 4. represent the right and left hand side views of the wire-boxshown in Figs. 1 and 2. Fig. 5 represents a front view of the mechanismshown in Fig. 1. Figs. 6, 7, and 8 represent views of wire-boxes of thesame construction as shown in Figs. 1, 3, and 4, with the exception ofthe parts inserted in their upper surfaces. Fig. 9 represents a view ofthe lefthand side of the loom, in part, and showing a side view of thewire-box, Fig. 8, with its projection, which is a modification of theprojection shown in Figs. 6 and 7 Similar letters of reference indicatecorresponding parts in all the figures.

' A represents a wire-bar, attached to a post or frame of the loom B.Its inner end rests and slides upon a plate, G. This plate is soattached to the frame of the loom as to be easily removed therefrom. Forinstance, should I wish to attach the wire-bar to the horizontal shaft Dby means of the two arms D, which are shown broken off, then I purposeremovin g the plate 0, as it would not be required to support thewire-bar.

E represents the reciprocating driving-slide. This slide is moved bymeans of a link, E, staff E and connecting-rod E which is shown brokenofi. It will be seen that I have attached the lower end of the staff IEto the shaft D by means of a double-acting joint, E and made it (theshaft) rigid; but in the event of my using the two arms D to support thewire-bar, I do not intend to use the shaft D rigid, but to have it rock.

F represents a hook, which is attached to the slide E and reciprocatedwith it. F may be called a rigid hook, and be used as such to allintents and purposes by inserting a pin, F through said hook and intothe drivingslide, or it may be a spring-hook, as it is necessary attimes to remove a wire from the wirebar by hand, either when firstcommencing to weave on a new piece or when backing the loom in order tofind a broken thread. 111 these events it is of the greatest importancethat F should be of such construction as to yield or move on a fulcrumin such a way that it can be raised out of contact with the wirehead Gand be held up by a pin, F, or some other means, until it is desired tocommence operation with the loom, when the pin is removed andthe hookallowed to descend and engage with the wire-head. Now, inasmuch as it isnecessary to have the hook move loosely on the driving-slide, so as tobe raised or oscillated, I attach a spring, F to the slide, and have itbear upon the upper surface of a part of the hook, to prevent the hookfrom accidentally sllppin g or losing its hold of the wirehead, and alsofor the purpose of causing quick motion to be given to the hook forother purposes hereinafter mentioned.

I do not wish to confine myself to this particular kind of hook, asthere are many kinds of hooks or latches in common use that can or maybe adopted and used.

The director F (shown in Figs. 8 and 9) is yielding in its construction,so that after a wire is boxed and the hook has moved away from it thehook comes in contact with this yielding projection, which I have calleddirector F and bears or presses it down by sliding over it, and theinstant the hook leaves the end of it the director recovers its firstposition again, and forms a shoulder or an abutment to the hook, andprevents it rebounding to interfere with the wire next adjoining to theone to be withdrawn. Should the construeter wish to, he can sink or letdown this director F or the yielding part of it, into the top surface ofthe wire-box.

The wire-boxes, Figs. 1 and S, are shown filled with wires andwire-heads G The wires G2 are represented as protruding through the boxand broken off. In Fig. 1 the hook F is represented as having partlywithdrawn a wire from out the wire-box, and in Fig. 2 the hook isrepresented as just takinghold of the wirehead to withdraw it from outof the wire-box. In this figure the outer part of the box is removed orcut off, in order to show the wirehead G in the box, and also the shapeof it.

H and H represent the lay and shuttle-box of the loom. They may besupported and vibrated in any or" the known ways. Fig. 9 shows an endcross-sectioned view of or through the lay H, in order to show the endof the wirebox F and plate 0 passing and projecting through it, as shownat H Fig. 1.

The wire-bar, driving-slide, lay, and shuttlebox may be vibrated andreciprocated by cranks and cams, or any other well-known means. (Notshown.)

I wish it to be understood that the several parts shown in the drawingsare not made proportional one with the other, or on any scale; but Ihave endeavored to be very particular and careful to so explain myinvent-ion and its operation that one skilled in the art of buildinglooms for weaving piled fabrics can readily and easily proportion andput into proper positions in the loom all of the parts shown anddescribed without further explanation.

I claim as of my own invention- 1. The combination, with a wire-boxconstructed with its upper surface, or a portion thereof which iscontiguous to the wire-heads, lower than the upper surfaces of the saidwireheads, of the wire-bar, constructed to have a lateral movement, anda single reciprocating driving-slide moving on said wire-bar, andactuated by a vibrating rod connected therewith without the interventionof a secondary slide, the said driving-slide carrying a hook which isadapted to withdraw, control, and insert the pile-wire, substantially asand for the purpose set forth.

2. In combination with a wire box constructed, as described, with itsupper surface,

or a portion thereof which is contiguous to the wire-heads, lower thanthe upper surface of said wire-heads, mechanism for withdrawing thewires, and the spring-director, whereby the hook is prevented fromrebounding and
